  POLAUCHENIA 
  BIANNULATA, 
  new 
  species. 
  

  

  Male.— 
  Similar 
  in 
  color 
  to 
  protentor, 
  the 
  prothorax 
  bivittate 
  in- 
  

   stead 
  of 
  trivittate 
  on 
  disk 
  posteriorly, 
  and 
  the 
  mesothoracic 
  and 
  

   metathoracic 
  spines 
  black 
  instead 
  of 
  yellow. 
  The 
  apices 
  of 
  fore- 
  

   wings 
  are 
  not 
  uniformly 
  dark 
  brown 
  as 
  in 
  protentor, 
  but 
  have 
  an 
  

   elongate 
  yellow 
  mark 
  with 
  dark 
  spotting 
  in 
  center 
  about 
  one-third 
  

   of 
  the 
  width 
  of 
  wing. 
  The 
  principal 
  color 
  difference 
  lies 
  in 
  the 
  bi- 
  

   annulate 
  hind 
  tibia, 
  protentor 
  having 
  5 
  brown 
  annuli. 
  

  

  A 
  much 
  stouter 
  species 
  than 
  protentor, 
  the 
  length 
  of 
  head 
  and 
  

   thorax 
  combined 
  being 
  barely 
  over 
  two-thirds 
  that 
  of 
  the 
  abdomen, 
  

   whereas 
  in 
  protentor 
  they 
  almost 
  or 
  quite 
  equal 
  the 
  abdomen. 
  The 
  

   forewings 
  (fig. 
  66) 
  exceed 
  the 
  tip 
  of 
  abdomen 
  and 
  their 
  posterior 
  

   apical 
  margin 
  is 
  but 
  slightly 
  concave. 
  The 
  head 
  is 
  much 
  broader 
  

   and 
  shorter 
  than 
  in 
  protentor, 
  the 
  interocular 
  space 
  is 
  much 
  narrower 
  

   than 
  one 
  eye, 
  the 
  mesothoracic 
  thorn 
  is 
  short, 
  the 
  metathoracic 
  one 
  

   longer, 
  tapered, 
  and 
  neither 
  very 
  hairy. 
  Venter 
  about 
  as 
  in 
  pro- 
  

   tentor; 
  hypopygial 
  claspers 
  small, 
  slender, 
  and 
  slightly 
  upcurved 
  

   apically.
